Most wound dressings simply cover the injury and perhaps also kill harmful bacteria. The PAINT system goes much further, as it incorporates a pen that could one day allow doctors to paint a gelatinous healing ink right into wounds.

Chinese researchers say they've demonstrated a seawater electrolyzer that works as efficiently as a commercial freshwater electrolyzer for months on end without corroding itself to death. It also looks like these machines could harvest lithium, too.

A huge chunk of energy usage goes towards heating and cooling homes and buildings, so it’s important to find new ways to regulate temperature passively. A new wood-based foam could drastically cool buildings to a degree that can be easily tuned.

It can be tricky enough getting titanium implants to bond with the surrounding bone, but when the patient has osteoporosis, things get even harder. An experimental coating may help, though, by first boosting and then blocking inflammation.

Researchers in China have demonstrated a quantum communication network where entangled photons are beamed between drones and ground stations, successfully maintaining their quantum link over a distance of 1 km.

Debate is raging about whether ancient flying reptiles called pterosaurs had feathers or not. Years ago a study found fossil evidence of protofeathers, but now another team claims the evidence doesn’t stack up, and the creatures were instead bald.

Skin-worn flexible electronics show great promise, in applications ranging from health monitoring to gesture control. The devices could soon also be more eco-friendly, as scientists have recently developed a method of making them from fish scales.

In what may be either the most discreet or the most conspicuous of wearable electronics, a team of researchers led by Desheng Kong has developed a prototype stretchable stopwatch sticker that can be adhered to the back of a person's hand.

A new study paints pterosaurs as far cuddlier creatures than we might have thought. According to an international team of palaeontologists, pterosaurs were covered in no less than four different types of feathers, pushing back the origin of this bodily covering by about 70 million years.

Although you may sniff meat to see if it's OK to eat, doing so is a subjective method of detecting spoilage, as it's dependent on the sensitivity of your sense of smell. Scientists have now developed a more objective alternative, in the form of a gas sensor that communicates with your smartphone.
